“METRONOME (Endangered)”: This is the 10th molecule of the projected 15 of the Endangered Grid. The "Endangered Grid" is part of the Score Movie for my projected in-progress 'opera' called "Endangered Languages, Endangered Culture, Endangered Ideas". 2 of the molecules are on my onesownthoughts YouTube channel. The other 7 are on Vimeo. - November 13, 2016 notes from tENTATIVELY, a cONVENIENCE
